Description

Technical Field

[0001] The utility model relates to the field of vehicle parts, in particular to a vehicle hinge. Background Art

[0002] Automotive hinges are devices used to connect vehicle doors. Their quality directly affects the sealing performance of the vehicle, the convenience of opening and closing the doors, and driving safety. Hinge, also known as hinge or door hinge, is a mechanical device used to connect two solids and allow them to rotate relative to each other. Its main feature is that it can provide a buffering effect when the cabinet or door is closed, minimizing the noise generated by the collision with the body when closing. Automotive hinges are commonly used in automotive doors, engine hoods, tailgate covers, fuel tank cover hinges, etc. In order to allow the driver and passengers to enter the car from the outside and return from the inside to the outside, there are doors. In order to connect the door and the body, the hinge is responsible for connecting the door and the body to ensure the opening and closing of the door, so there is a door hinge. The installation surface between the door hinge, the door and the body must be flat. If the door hinge is connected with bolts, the relative size between the bolt mounting holes of the body and the door component must be consistent and stable. The function of the door hinge is to ensure and facilitate the opening and closing of the door. Because the use of the car has a certain warranty period, we not only require the door hinge to meet this function when it is just shipped, but also to maintain this function after a period of use or a certain number of times the door is opened and closed. Traditionally, either two curved shafts connect the two ends, with too few stress points and easy damage, and some parts are damaged and inconvenient to disassemble, or the upper fixing device and the lower fixing device are connected by the middle shaft. The structure is not firm. For this reason, we have proposed a car hinge. Utility Model Content

[0036] Working principle: When the door needs to be closed, the large door fixing groove A11 and the small door fixing groove A12 fix the entire door assembly 1 on the door through screws, and the large opening groove B14 and the small opening groove B15 also fix the entire body assembly 2 on the body through screws. The door is pushed, and the door drives the door key 5 to rotate. The door key 5 rotates on the cylinder 18, and the hexagon 22 does not rotate. At the same time, the hexagon 22 is kneaded and connected with the hexagonal hole 8, so that the door assembly 2 does not rotate. During the rotation of the door key 5 on the cylindrical shaft 22, the entire door assembly 1 is driven to rotate. The door assembly 1 rotates so that the triangular fixing plate 4 fits with the rectangular groove 13 between the vehicle body, thereby completing the door closing action. When the door needs to be opened, the door is pushed, and the door drives the door key 5 to rotate. The door key 5 rotates on the cylinder 22, and the hexagon 22 does not rotate. At the same time, the hexagon 22 is pinched and connected with the hexagonal hole 8, so that the door assembly 2 does not rotate. During the rotation of the door key 5 on the cylindrical shaft 22, the entire door assembly 1 is driven to rotate. The door assembly 1 rotates, so that the triangular fixing plate 4 is separated from the rectangular groove 13 between the vehicle body, thereby completing the door opening action.
